| 摘 要： | 东营凹陷沙三段烃源岩中发现一些规模不大的玄武岩和辉长岩体。通过对其岩性及产状、岩石化学和地球化学元素分析，认为研究区玄武岩是碱性－亚碱性橄榄玄武岩；辉长岩的岩石化学和微量元素组成与上述玄武岩相似，认为它们具有同源性，只是辉长岩没有喷发到地表而被封存在刚刚沉积下来的沙三段烃源岩中。水下喷溢的玄赋岩对烃源岩的沉积和生烃演化具有促进作用，辉长岩可以造成局部烃源岩的热变质作用。

| Abstract: | Igneous rocks of basalt and gabbro have been discovered within the hydrocarbon source rocks in the Third Member of the Shahejie Formation in the Dongying depression.Research on the 1ithology, textures, chemical composition and trace elements of the basalt and gabbro showed that the basalts are exactly alkali or sub alkali olivinebasalts.Chemical compostions and trace elements of the gabbro are derived similar to those of the basalts, so the gabbro and basalt are considered to have the same genetic source derived from the mantle.The gabbro intruded into the source rocks,instead of going up and flowing out on the surface. |
